/u/porn was active here briefly, make a load of communitiess like /c/Boobs and has since not been on, leaving those communities unmoderated. I’ve messaged them about being added to some of them (like they offered), but no reply.
I think the larger communities, at least, should have more than one moderator to cover different timezones, being unavailable or disappearing. I assume that admins can add moderators to comms, right?
My point is that only /u/porn (or an admin?) can add another moderator to their subs, and given that they’re not on we already have popular comms without mods.
I think if you start a community here, you should at least add a few posts to get the ball rolling and then stick around to moderate and/or build a mod team.
I think for this you really need to rope in the admins to create a system for installing moderators to unmoderated communities. That, however, can only happen once there are enough active mods on the site to begin with, which will take time.
